Made the AppMetadataStore and ScheduleStore compatible with an older data format where the app version was not present, so that it is no longer necessary to update these records to the new format in the Upgrade Tool.

Description

We used to perform the change of data formats from pre-appversion to appversion data format in three Stores - DatasetBasedStreamSizeScheduleStore, DatasetBasedTimeScheduleStore, AppMetaStore, in the upgrade tool. We need to remove that change of data during upgrade step and instead make the Store work with both old and new data formats.
